How important is tyre size for stock rims on a MPS6?

[lup15]

whats your budget? I had the KU36 installed for about 260 per corner. my suspension is letting down the tyres atm

[shakespeare]

Has any one run the Goodyear Eagle F1 Asymmetric?the K31's arnt as cheep as i was expecting and they are not that far these Goodyears at the moment..?

Hey Pete,

I ran these on 7.5" rims (225/40/18) found them quite grippy and quieter than the bridgestones. However I ran into some diff related issues when I played with tyre sizes don't know how much this was tyre size or just my dodgy diff, but I had to have forward mount bolts replaced then a cracked rear mount replaced, finally I went back to stock tyre sizes and installed new CP-e and Turbine Tech mounts, never gave me trouble again after that!

I think as long as all 4 wheels have the same diameter you shouldn't run into too many issues, like I said above it may have been just mine that had the tyre size issues!

This thread covers most of it

Cheers
Chris


Mazda 6 MPS Differential problems and/or solutions

Oh man now u have got me thinking...

I remember this thread and didn’t want any issues with my MPS. as it is my Wife’s daily drive.

however the 215/45r18's are as rare as rocking horse shit. and are not a supported size for many of the manufacturers.

this is frustrating as the car is running on her space saver and it is a wide as the tyres on my downhill mountain bike...

what size are other MPS6 members running and with what results?

After all my ginning round i have finally made a decision on tyres for the stock rims. Despite what the websites and some tyre shops will say both Kumho (KU31, KU21), Falken (912) and Hankook (V12EVO) do these tyres in our OEM size.
The Hankook V12EVO was $60 cheaper a tyre than the Ku31. So the choice was easy. I'm having a set off V12Evo’s fitted for a great price by a tyre guy who knows what he is talking about today. I will update how they go as they scrub in.

But I am stoked to have it all sorted.

jesus... how expensive were the KU31's? should have been able to pick them up for 150-180 a corner...
how much you paying for the V12 EVO's?

[Pistol Pete]

hahahah... nope this is WA mate nothing is cheap over here…


the best price I got on KU31’s was $300 a tyre. The worst was $380. I also got offerd $350 on the KU21's?
In the end I paid $245 a tyre for the Hankooks V12 Evo’s. I felt it was a great price on these tyres and I definitely did my homework and ringing round and it turned out to be by far the cheapest on those as well.
All for a 215/45R18 fitted and balanced with the roadside Hankook warranty.

Holy crap!
Thats the disadvantage of the mining boom i assume. Cost of everything goes up because there is more money around.
Surely you could have got them cheaper from the eastern states and has them posted over and still be ahead?
We sent a set of MPS rims and tyres to Tassie for $80, so can't assume it would be much more to WA.l

Important question is - What do you think of the tyres?

[Pistol Pete]

I think they are great all day every day daily drive tyres.
They seem to provide great grip (not that the MPS6 needs much help however they have considerably reduced understeer) they are quiet and comfy.

Only drawback I can see so far is that they muffle the small amount of feedback through the steering wheel that was there with the existing Pirelli tyres. And have slightly muted overall steering feel. There is a slight squidge on turn in that wasn’t as noticeable before.

However in saying all that they perfectly fit the bill for why I bought the car. Comfy, great mile eater on holidays and hwy/freeway work, good ride/handling balance.
